●Description

BD9207FPS is a LED driver with built-in step-down switching regulator and incorporates the built-in switching MOS EFT of Pch. Feedback voltage is as low as 0.2V and can suppress the loss on the sense resistance of LED.

It is operated by PWM method with an oscillating frequency of 900 KHz and can use smaller coil than a switching regulator of low-frequency operation.

●Features

 1)  Maximum switching current of 1.5A

 2)  Built-in Pch switching MOS FET for high efficiency

 3)  Low loss because feedback voltage is as low as 0.2V

 4)  High oscillating frequency of 900KHz   (Fixed)

 5)  Built-in soft start function

 6)  Built-in overcurrent protection circuit (OCP)

 7)  Built-in thermal shutdown circuit (TSD)

 8)  ON/OFF of output is possible by STBY terminal.

 9)  Compact surface-mount TO252S-5 package

●Applications

・For use in the light sources of PPC

・Printer etc. and the LCD backlights ofLED lighting apparatus & monitor

・Note PC etc.
